Serial No. 251,720.

quickly adjust the ends of the rollers longitudinally of the side rails of the conveyer and thereb readily secure the proper lead for the en s of the rollers. .Moreover, on' straight conveyers having either a single or multiple row of rollers, it likewise is often desirable to arrange the rollers at some angle other than a right angle to the conveyer frame and to provide means for readily .adjusting the angle of the rollers.

In the accompanying drawing I have shown a preferred construction by which the desired results above referred to may advantageously be secured. In this showing,

This invention Vrelates to conveyers and more particularly to attac ents for roller conveyers by means of which the ends of the rollers at the eurvesof a conveyer may be moved longitudinall of the side rails of the conveyer in order that the packages which are being conveyed will not contact with the side rails.

An important object of the invention is to provide a simple, eiiicient and relatively inexpensive device of the character referred to.

Another object of the invention is to prothe rollers of a roller which the ends of the rollers may be easily and quickly moved lon- Figure 1 is a plan view of a curved roller gitudinall of the side rails of the conveyer. conveyer, j l Othero jects and advantages of the inven- Figure 2 is a similar view of a straight portion of a roller conveyer,

Figure 3 is a similar viewof a conveyer having a plurality of rows of rollers.

Figure 4 is a detail view in side elevation of a portion of the device, and,

Figure 5 is a section on line 5--5 of Figure 4.

Referring to the drawing, numerals 10 and 11 designate side rails of a conveyer, such rails preferably being formed of steel angle irons as clearly shown vin Figure 5. A plurality of rollers 12 provided with stub shafts 18 are journaled in the side rails 10 and 11 and secured in position by means of cotter pins 13'. `As shown in Figures 4 and 5, the side rails 10 and 11 are providedjwith a plurality of elongated substantially horizontal slots 14 and 15 forming bearings for the shafts of the rollers. Plates or strips tion willbecome apparent from the following description. In conveying packages around a curve of a roller conveyer, it is desirable to provide means for preventing the violent contact of the packages with .the sides of the conveyer. This result may be accomplished in numerous ways such as by mounting the rollers in a plurality of sections and rotating those sectionsnearest the outside rail at a faster rate of speed than the sections of the rollers which are nearest the inside rail. Another Way in which the desired result may be accomplished is byl forming the rollers in such manner that the diameter of the portions of the rollers adjacent the outside rail of the conveyer is greater than the diameter of the portions of the rollers adjacent the inside rail of the conveyer. v Another method of accomplishing the result desired is by employing rollers having the same diameter throughout their lengths but so arranged that one of their ends leads the other ends, or in other words,

ranged adjacent and in contact with the outside faces of the rails 10 and 11. These plates are provided with openings 17 and 18 which substantially correspond in shape 01de' Wlth the mdu of the conveyer- Curve' and size to the shape and size of the shafts .The amount of lead of the ends of the rollers cannot be satisfactorily determined theoretof ,the rollers 12- The Plates 16 are also ically but must be determined by experiments provlfed mtefmefhate the Openmgs 17 and carried out under the exact conditions under 18 W1th longitudinal slots 19. At `varlmis which the conveyer will be operated when in points 1n the side rails 10 corresponding 1n actual use. For this reason it is highly deosition to the slots 19, the side rails are sirable that the conveyerbe provided with P provided with openings 20 adapted to receive means by which the user may simply and olts 21 which together with the nuts 22,

16, preferably made of light steel are ar-A are adapted to secure the plates 16 to the rails 10.

ment of the plate 16 effects a corresponding movement of the ends of the rollers because of the fact that the shafts of the rollers are received in the openings 17 and 18 in the plate 16. When the ends of the rollers have een moved tothe desired point, the nuts are tightened on the bolts 21 thereby securing theplate 16 Ain position so that it cannot be moved longitudinally with respect to the side rails of the conveyer, thus preventing movement of the ends of the rollers longitudinally of; the-conveyer frame. It Will be apparent that either or both or the plates 16 may be moved longitudinally of the rails 10 and 11 thereby providing a relatively great movement of the rollers l2 with respect to the side rails.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope o the subjoined claims.
